Marcel Duchamp submitted Fountain to The Society of Independent Artists in order to
B. challenge their claims that they would accept any work of art for their exhibition.
Step-by-step explanation:
Marcel Duchamp was an avant garde artist in the early 20th century who submitted Fountain, a sculpture piece consisting of a ready made toilet which was signed as 'R.Mutt' to The Society of Independent Artists for exhibition.
It caused huge controversy but it had to be exhibited because the gallery had the rule to exhibit anything that is submitted if the artist had paid the fee required.
Marcel was challenging the idea that a fee can decide what can be showcased as art and what cannot.
